Is it possible for an atheist to believe in an after-life?

I know this is a dumb question but its bugging me. As an atheist from the age of 9 I was always a little envious of religious people as they had the hope (no matter how illogical) of an after-life. All I had to look forward to as an atheist was being worm food. Last week-end after quite a few rum and cokes I came up with an idea how an atheist could legitimately have the hope of an afterlife. It is based on the theory of the Big Bang. This theory explains how the universe was created but cannot explain how the original expansion of the universe occurred from nothing. I had the idea that it did not occur from nothing but in fact occurred from the expansion of a previously contracted universe. The theory is that the universe expands out from its state of maximum contraction until it reaches its maximum expansion and then contracts back. This process is infinite as energy cannot be created or destroyed but merely changed from one form to another. If this process is indeed infinite then at some point I will exist again (and again) in another universe under slightly differing circumstances each time.

I created a webpage which explains the idea better and would appreciate it if people could take a look and criticize the logic. The page is http://bangism.wordpress.com/

Please just take a minute to look and let me know if it makes sense or if I have totally lost the plot.

As an atheist I would have thought you would have been able to put forward a logical counter argument to what I posted. Blind disbelief is just as bad as blind belief. Has atheism really become just another blind faith religion with no logical discussion?

Hey Fuck wit! One minute you have an unshackeable faith and belief in Sharia law the next minute you believe your future life is pushing up daisies. I believe your future involves lots of medication, restraining orders and padded rooms.
